In the form of CATV cable, coaxial cable provides a cheap means of transporting multi-channel television signals around metropolitan areas. It is also used
by large corporations in building security systems.

The data transmission characteristics of the coaxial cable are better than those of twisted pair. Therefore, this opens the possibility of using the
coaxial cable as the basis for a shared cable network, with part of the bandwidth being used for the data traffic.

Types of Coaxial Cable

There are basically two types of the coaxial cable that are given here:

Thicknet

Thinnet

Let's discuss in detail about the above two types of coaxial cable.

Thinnet Cable

Thinnet cable was the first cable that was used in network cable. This cable was used in
approximately 1995-1996.

Thinnet cable was only used in bus topology.

Thinnet cable also known as IEEE 10base-2. Here IEEE is an institution that decides the
standards of all the cable.

Here 10 means data transmission rate of 10Mbps and 2 is the maximum segment length. The
exact distance of this is 185metre.

When we buy a cable, then there are two most important thing to notice, the data transmission
rate that the cable is of how much mbps or gbps speed, and second is the segment length, decides
how many maximum data can be transferred by the cable without cutting.

The thinnet cable uses Baseband signal to transfer the data. In baseband, there is only signle
frequency, and in case of broadband there are multiple frequency.

The connector used in thinnet cable called as BNC (barrel net connector) T type
connector.
